White Papers and Documents

This whitepaper introduces the reader to an entirely new scheme for lossless audio compression called aptX Lossless. Briefly and simply, by employing dynamic adaptation techniques to a greater and more intelligent extent than conventional schemes, aptX Lossless, offers significant benefits over existing lossless audio codecs, and attains better coding scalability and run-time trade-offs as a result. These benefits are of considerable importance to strongly emerging applications for high-definition forms of digital entertainment, especially those deployed in the wirelessly networked, broadband home, and those portable systems being developed for consumers on the move.

CSR is a member of the Cambridge White Spaces Consortium that has set up a TV White Spaces Trial to determine if new unlicensed services could coexist with incumbent licensed services such as DTT and PMSE. This report specifically addresses PMSE with the Neul WhiteSpace devices (WSD) using the Weightless specification.
